RESUMEN

BACKGROUND: Young people receiving cancer treatment in the South Thames Children's, Teenagers' and Young Adults' Cancer Operational Delivery Network usually receive care across two or more NHS trusts, meaning transition into adult services can be challenging. AIM: To develop a planned, co-ordinated approach to transition across the network that meets National Institute for Health and Care Excellence guidance recommendations for transition and the cancer service specifications. METHODS: A 2-year, nurse-led quality improvement (QI) project, using the principles of experience-based co-design. OUTCOMES: The QI project resulted in the development of six key principles of practice; refining and testing of a benchmarking tool; initiatives to facilitate first transition conversations; and the launch of an information hub. CONCLUSION: Robust QI processes, cross-network collaboration and wide stakeholder involvement required significant resource, but enabled deeper understanding of existing pathways and processes, facilitated the establishment of meaningful objectives, and enabled the testing of interventions to ensure the project outcomes met the needs of all stakeholders.

RESUMEN

Randomized trials provide high-quality, internally consistent data on selected clinical questions, but lack generalizability for the aging population who are most often diagnosed with cancer and have comorbid conditions that may affect the interpretation of treatment benefit. The need for high-quality, relevant, and timely data is greater than ever. Promising solutions lie in the collection and analysis of real-world data (RWD), which can potentially provide timely insights about the patient's course during and after initial treatment and the outcomes of important subgroups such as the elderly, rural populations, children, and patients with greater social health needs. However, to inform practice and policy, real-world evidence must be created from trustworthy and comprehensive sources of RWD; these may include pragmatic clinical trials, registries, prospective observational studies, electronic health records (EHRs), administrative claims, and digital technologies. There are unique challenges in oncology since key parameters (eg, cancer stage, biomarker status, genomic assays, imaging response, side effects, quality of life) are not recorded, siloed in inaccessible documents, or available only as free text or unstructured reports in the EHR. Advances in analytics, such as artificial intelligence, may greatly enhance the ability to obtain more granular information from EHRs and support integrated diagnostics; however, they will need to be validated purpose by purpose. We recommend a commitment to standardizing data across sources and building infrastructures that can produce fit-for-purpose RWD that will provide timely understanding of the effectiveness of individual interventions.

RESUMEN

In the Netherlands, one out of two people will be confronted with the diagnosis of cancer sometime in their life. Against this increased number of patients, a large proportion luckily can be cured. Today, a rather high proportion of people receive treatment to control cancer growth or stabilize the disease, sometimes, for the rest of their lives. If such long-standing treatment is administered for more than 10-20 years, the stage of cancer is presently often not referred to as "palliative" anymore, but much more often as "chronic." It could be argued that regardless of the cancer disease stage you are in and whether you are or can be cured, your cancer diagnosis nevertheless has become part of your life, including the experience of chronicity. Discussions surrounding the chronicity of cancer in the context of cancer are still ongoing. This is especially the case because "experiencing chronicity" is dependent on the type of cancer and is less applicable in cancers where the prognosis is often less than one year, such as is more frequently the case with lung or pancreatic cancer. In all situations, experiencing chronicity nevertheless brings along uncertainty, either with or without chronic stress. Combatting stress by choosing the right wording, maintaining an optimistic stance along with physical activity and/or psychosocial education seems important to optimize well-being and to stabilize tumor growth or remove the tumor. In conclusion, chronicity in the context of treating and caring for cancer seems a somewhat gray area. However, regardless in how we, as medical professionals, speak about cancer with long-standing disease trajectories (that sometimes even can be cured), it first of all seems important to approach, take care, and treat patients well. This can facilitate discussions with patients about their disease and disease experiences. Moreover, it can stimulate patients themselves to take responsibility for their own health, which can be of added value to the entire disease trajectory.

RESUMEN

Background: How to ingeniously design multi-effect photosensitizers (PSs), including multimodal imaging and multi-channel therapy, is of great significance for highly spatiotemporal controllable precise phototherapy of malignant tumors. Methods: Herein, a novel multifunctional zinc(II) phthalocyanine-based planar micromolecule amphiphile (ZnPc 1) was successfully designed and synthesized, in which N atom with photoinduced electron transfer effect was introduced to enhance the near-infrared absorbance and nonradiative heat generation. After simple self-assembling into nanoparticles (NPs), ZnPc 1 NPs would exhibit enhanced multimodal imaging properties including fluorescence (FL) imaging (FLI) /photoacoustic (PA) imaging (PAI) /infrared (IR) thermal imaging, which was further used to guide the combined photodynamic therapy (PDT) and photothermal therapy (PTT). Results: It was that under the self-guidance of the multimodal imaging, ZnPc 1 NPs could precisely pinpoint the tumor from the vertical and horizontal boundaries achieving highly efficient and accurate treatment of cancer. Conclusion: Accordingly, the integration of FL/PA/IR multimodal imaging and PDT/PTT synergistic therapy pathway into one ZnPc 1 could provide a blueprint for the next generation of phototherapy, which offered a new paradigm for the integration of diagnosis and treatment in tumor and a promising prospect for precise cancer therapy.

RESUMEN

Background: Chimeric antigen receptor T (CAR-T) cell therapies have achieved remarkable success in the treatment of hematological tumors. However, given the distinct features of solid tumors, particularly heterogeneity, metabolic aggressiveness, and fewer immune cells in tumor microenvironment (TME), the practical utility of CAR-T cells for solid tumors remains as a challenging issue. Meanwhile, although anti-PD-1 monoclonal antibody (mAb) has shown clinical efficacy, most mAbs also show limited clinical benefits for solid tumors due mainly to the issues associated with the lack of immune cells in TME. Thus, the infiltration of targeted immunological active cells into TME could generate synergistic efficacy for mAbs. Methods: We present a combinational strategy for solid tumor treatment, which combines armored-T cells to express Fc-gamma receptor I (FcγRI) fragment on the surfaces for targeting various tumors with therapeutically useful mAbs. Choosing CD20 and HER-2 as the targets, we characterized the in vitro and in vivo efficacy and latent mechanism of the combination drug by using flow cytometry, ELISA and other methods. Results: The combination and preprocessing of armored T-cells with corresponding antibody of Rituximab and Pertuzumab exerted profound anti-tumor effects, which is demonstrated to be mediated by synergistically produced antibody-dependent cellular cytotoxicity (ADCC) effects. Meanwhile, mAb was able to carry armored-T cell by preprocessing for the infiltration to TME in cell derived xenograft (CDX) model. Conclusions: This combination strategy showed a significant increase of safety profiles from the reduction of antibody doses. More importantly, the present strategy could be a versatile tool for a broad spectrum of cancer treatment, with a simple pairing of engineered T cells and a conventional antibody.

RESUMEN

Purpose: To address the problem of suboptimal reactive oxygen species (ROS) production in Radiation therapy (RT) which was resulted from exacerbated tumor hypoxia and the heterogeneous distribution of radiation sensitizers. Materials and Methods: In this work, a novel nanomedicine, designated as PLGA@IR780-Bi-DTPA (PIBD), was engineered by loading the radiation sensitizer Bi-DTPA and the photothermal agent IR780 onto poly(lactic-co-glycolic acid) (PLGA). This design leverages the tumor-targeting ability of IR780 to ensure selective accumulation of the nanoparticles in tumor cells, particularly within the mitochondria. The effect of the photothermal therapy-enhanced radiation therapy was also examined to assess the alleviation of hypoxia and the enhancement of radiation sensitivity. Results: The PIBD nanoparticles exhibited strong capacity in mitochondrial targeting and selective tumor accumulation. Upon activation by 808 nm laser irradiation, the nanoparticles effectively alleviated local hypoxia by photothermal effect enhanced blood supplying to improve oxygen content, thereby enhancing the ROS production for effective RT. Comparative studies revealed that PIBD-induced RT significantly outperformed conventional RT in treating hypoxic tumors. Conclusion: This design of tumor-targeting photothermal therapy-enhanced radiation therapy nanomedicine would advance the development of targeted drug delivery system for effective RT regardless of hypoxic microenvironment.

RESUMEN

Background: The interaction between pyroptosis-a form of programmed cell death-and tumor immunity represents a burgeoning field of interest. Pyroptosis exhibits a dual role in cancer: it can both promote tumor development and counteract it by activating immune responses that inhibit tumor evasion and encourage cell death. Current tumor immunotherapy strategies, notably CAR-T cell therapy and immune checkpoint inhibitors (ICIs), alongside the potential of certain traditional Chinese medicinal compounds, highlight the intricate relationship between pyroptosis and cancer immunity. As research delves deeper into pyroptosis mechanisms within tumor therapy, its application in enhancing tumor immune responses emerges as a novel research avenue. Purpose: This review aims to elucidate the mechanisms underlying pyroptosis, its impact on tumor biology, and the advancements in tumor immunotherapy research. Methods: A comprehensive literature review was conducted across PubMed, Embase, CNKI, and Wanfang Database from the inception of the study until August 22, 2023. The search employed keywords such as "pyroptosis", "cancer", "tumor", "mechanism", "immunity", "gasdermin", "ICB", "CAR-T", "PD-1", "PD-L1", "herbal medicine", "botanical medicine", "Chinese medicine", "traditional Chinese medicine", "immunotherapy", linked by AND/OR, to capture the latest findings in pyroptosis and tumor immunotherapy. Results: Pyroptosis is governed by a complex mechanism, with the Gasdermin family playing a pivotal role. While promising for tumor immunotherapy application, research into pyroptosis's effect on tumor immunity is still evolving. Notably, certain traditional Chinese medicine ingredients have been identified as potential pyroptosis inducers, meriting further exploration. Conclusion: This review consolidates current knowledge on pyroptosis's role in tumor immunotherapy. It reveals pyroptosis as a beneficial factor in the immunotherapeutic landscape, suggesting that leveraging pyroptosis for developing novel cancer treatment strategies, including those involving traditional Chinese medicine, represents a forward-looking approach in oncology.

RESUMEN

The Suppressor of Cytokine Signaling (SOCS) family proteins are important negative regulators of cytokine signaling. SOCS1 is the prototypical member of the SOCS family and functions in a classic negative-feedback loop to inhibit signaling in response to interferon, interleukin-12 and interleukin-2 family cytokines. These cytokines have a critical role in orchestrating our immune defence against viral pathogens and cancer. The ability of SOCS1 to limit cytokine signaling positions it as an important immune checkpoint, as evidenced by the detection of detrimental SOCS1 variants in patients with cytokine-driven inflammatory and autoimmune disease. SOCS1 has also emerged as a key checkpoint that restricts anti-tumor immunity, playing both a tumor intrinsic role and impacting the ability of various immune cells to mount an effective anti-tumor response. In this review, we describe the mechanism of SOCS1 action, focusing on the role of SOCS1 in autoimmunity and cancer, and discuss the potential for new SOCS1-directed cancer therapies that could be used to enhance adoptive immunotherapy and immune checkpoint blockade.

RESUMEN

Importance: Serious illness conversations (SICs) that elicit patients' values, goals, and care preferences reduce anxiety and depression and improve quality of life, but occur infrequently for patients with cancer. Behavioral economic implementation strategies (nudges) directed at clinicians and/or patients may increase SIC completion. Objective: To test the independent and combined effects of clinician and patient nudges on SIC completion. Design, Setting, and Participants: A 2 × 2 factorial, cluster randomized trial was conducted from September 7, 2021, to March 11, 2022, at oncology clinics across 4 hospitals and 6 community sites within a large academic health system in Pennsylvania and New Jersey among 163 medical and gynecologic oncology clinicians and 4450 patients with cancer at high risk of mortality (≥10% risk of 180-day mortality). Interventions: Clinician clusters and patients were independently randomized to receive usual care vs nudges, resulting in 4 arms: (1) active control, operating for 2 years prior to trial start, consisting of clinician text message reminders to complete SICs for patients at high mortality risk; (2) clinician nudge only, consisting of active control plus weekly peer comparisons of clinician-level SIC completion rates; (3) patient nudge only, consisting of active control plus a preclinic electronic communication designed to prime patients for SICs; and (4) combined clinician and patient nudges. Main Outcomes and Measures: The primary outcome was a documented SIC in the electronic health record within 6 months of a participant's first clinic visit after randomization. Analysis was performed on an intent-to-treat basis at the patient level. Results: The study accrued 4450 patients (median age, 67 years [IQR, 59-75 years]; 2352 women [52.9%]) seen by 163 clinicians, randomized to active control (n = 1004), clinician nudge (n = 1179), patient nudge (n = 997), or combined nudges (n = 1270). Overall patient-level rates of 6-month SIC completion were 11.2% for the active control arm (112 of 1004), 11.5% for the clinician nudge arm (136 of 1179), 11.5% for the patient nudge arm (115 of 997), and 14.1% for the combined nudge arm (179 of 1270). Compared with active control, the combined nudges were associated with an increase in SIC rates (ratio of hazard ratios [rHR], 1.55 [95% CI, 1.00-2.40]; P = .049), whereas the clinician nudge (HR, 0.95 [95% CI, 0.64-1.41; P = .79) and patient nudge (HR, 0.99 [95% CI, 0.73-1.33]; P = .93) were not. Conclusions and Relevance: In this cluster randomized trial, nudges combining clinician peer comparisons with patient priming questionnaires were associated with a marginal increase in documented SICs compared with an active control. Combining clinician- and patient-directed nudges may help to promote SICs in routine cancer care. Trial Registration: ClinicalTrials.gov Identifier: NCT04867850.

RESUMEN

BACKGROUND: The number of cancer survivors has increased in recent decades, and the majority of them suffer from sequelae of their disease and treatment. This study, which is part of the larger research project OPTILATER, aims to explore different aspects of care services for long-term survivors (≥ 5 years after initial cancer diagnosis) in Germany. The study places an emphasis on the situation of people from different age groups, with different socio-demographic and cultural backgrounds, and sexually and gender diverse individuals. METHODS: To investigate experiences related to follow-up care, focus groups (n = 2) will be conducted with members of patient advisory councils and advocacy groups, representatives of communities, healthcare workers and networks, as well as members of Associations of Statutory Health Insurance Physicians. Guided interviews will be carried out with patients and relatives (n = 40) to investigate needs, barriers and obstacles in terms of follow-up care. On this basis, additional focus groups (n = 2) will be carried out to derive possible scenarios for improving the consideration of needs. Focus groups and interviews will follow a semi-structured format and will be analysed content-analytically. Focus groups and interviews will be conducted online, recorded, transcribed, and analysed independently by two persons. DISCUSSION: The qualitative approach is considered suitable because of the exploratory research aims. The identification of experiences and barriers can reveal disparities and optimization potential in the care of long-term cancer survivors.

RESUMEN

The development of therapeutic drugs and methods has been greatly facilitated by the emergence of tumor models. However, due to their inherent complexity, establishing a model that can fully replicate the tumor tissue situation remains extremely challenging. With the development of tissue engineering, the advancement of bioprinting technology has facilitated the upgrading of tumor models. This article focuses on the latest advancements in bioprinting, specifically highlighting the construction of 3D tumor models, and underscores the integration of these two technologies. Furthermore, it discusses the challenges and future directions of related techniques, while also emphasizing the effective recreation of the tumor microenvironment through the emergence of 3D tumor models that resemble in vitro organs, thereby accelerating the development of new anticancer therapies.

RESUMEN

PURPOSE: The study aims to explore unmet social needs and sources of financial toxicities in patients as noted by health care professionals and researchers in cancer supportive care, shedding light on potential health disparities. METHODS: In this cross-sectional survey, we anonymously surveyed active members of the Multinational Association of Supportive Care in Cancer (MASCC). The survey, structured in three sections, included questions regarding the routine assessment of social needs during patient consultations, sociodemographic aspects, factors influencing financial toxicity (FT), perceived support for managing FT, and available/desirable resources. RESULTS: A total of 218 MASCC members were included, predominantly from high-income countries (HIC, 73.4%), with many age 41-60 years (56.5%) and female (56.9%). Drug/treatment cost and insurance coverage were the main sources for FT among the HIC, whereas participants from low-middle-income countries (LMIC) considered transportation cost, loss of employment because of cancer diagnosis, and unavailability of return-to-work services as the top three sources of FT. Respondents from LMIC (adjusted odds ratio [aOR], 3.01 [95% CI, 1.15 to 7.93]) and physicians (aOR, 2.67 [95% CI, 1.15 to 6.21]) were more likely to routinely assess financial coverages. Socioeconomic status was consistently ranked as one of the top three sources of financial toxicities by participants from LMIC (34%), HIC excluding the United States (38%), those who do not self-identify as racial/ethnic minority (36%), and physicians (40%). CONCLUSION: This global survey of health care professionals and researchers in HIC and LMIC revealed varying approaches to assessing financial coverage and social needs. Socioeconomic status emerged as a consistent concern across countries, affecting financial toxicities. The study highlights the need for tailored approaches and improved resource visibility while emphasizing clinicians' pivotal role in addressing financial aspects of cancer care.

RESUMEN

BACKGROUND: Regardless of cancer type or stage of treatment, physical activity (PA) has been shown to reduce the risk of cancer recurrence and death. It is associated with a range of positive effects on patients' physical and psychological well-being, particularly in the areas of aerobic fitness, fatigue, mental health and perceived overall quality of life. However, in current oncology practice, the combination of its indication with treatment is still relatively rare. At the same time, cancer patients' participation in regular physical activity is usually very low. However, as PA is an effective method to support cancer treatment and plays an important role in prevention, it is necessary to find effective strategies to involve patients more widely in physical activities. To this end, physical activity programmes organised directly by facilities providing comprehensive cancer care appear to be very suitable. PURPOSE: This literature review maps the main barriers and facilitators to cancer patients' participation in physical activity programmes. In particular, economic factors related to health policy, reflected in the availability of this type of supportive care for patients, the level of health literacy, the organization of PA programs, health care providers - both physicians and health care workers, social support and intrapsychic influences on the part of patients play a major role. Since the implementation of physical activity programmes into the existing cancer care system is a rather challenging process, the paper also deals with the possibilities of using the Health Belief Model. In the given context, this model allows the prediction and identification of barriers and supportive factors to patients' involvement in PA programs in order to maximize their effectiveness and adapt them to the needs of patients and, at the same time, to the capabilities of a specific medical facility.

RESUMEN

BACKGROUND: Developing cancer in young adulthood is a non-normative life event and associated with adverse physical, social and psychological consequences. High psychological distress is common in AYA cancer patients including anxiety, depression or fear of recurrence. At the same time, it is well known that AYA often report unmet needs for support, particularly in terms of informational exchange and emotional support from peers in order to benefit from shared experiences and enhance self-efficacy. Especially in the AYA group, interactions with other same-aged cancer patients may represent an essential resource in terms of coping with the disease, as family members and friends are often overwhelmed and struggling with helplessness. Currently, there is a lack of professional support services using peer support (e.g. psycho-oncological support, aftercare consultations, social legal counselling) or evaluated peer support interventions in Germany. Our aim is to assess the effectiveness of the Peer2Me intervention for AYAs, in which acute patients (mentees) are accompanied by an AYA survivor (mentor) over a period of three months. METHODS: A prospective Comprehensive Cohort Design with repeated measures will be used to evaluate the effectiveness of Peer2Me for AYA. A sample of 180 patients in active cancer treatment aged 18 to 39 years will be enrolled and randomized to the intervention or control condition (a single AYA-specific consultation). Following mentor training, mentees and mentors are matched by diagnosis, age, and gender. The primary outcome is self-efficacy; secondary outcomes include measures of anxiety, depression, health literacy, life satisfaction and social support life. Outcomes will be measured at baseline before the intervention (t1), immediately after completion of the three-month intervention (t2) and three months after completion the intervention (t3). For the final analyses, we will use an intention-to-treat approach (ITT) and compare patients in the assigned treatment groups. DISCUSSION: Peer2Me might be an important addition to existing professional psychosocial support services for young cancer patients. At the end of the study, a psycho-oncological intervention for young cancer patients undergoing acute treatment should be available, from which both mentors and mentees could benefit. The long-term continuity of Peer2Me should be ensured through collaboration with different partners. TRIAL REGISTRATION: The study was retrospectively registered on February 4, 2022 at clinicaltrials.gov (NCT05336318).

RESUMEN

The application of graphene-based nanocomposites for therapeutic and diagnostic reasons has advanced considerably in recent years due to advancements in the synthesis and design of graphene-based nanocomposites, giving rise to a new field of nano-cancer diagnosis and treatment. Nano-graphene is being utilized more often in the field of cancer therapy, where it is employed in conjunction with diagnostics and treatment to address the complex clinical obstacles and problems associated with this life-threatening illness. When compared to other nanomaterials, graphene derivatives stand out due to their remarkable structural, mechanical, electrical, optical, and thermal capabilities. The high specific surface area of these materials makes them useful as carriers in controlled release systems that respond to external stimuli; these compounds include drugs and biomolecules like nucleic acid sequences (DNA and RNA). Furthermore, the presence of distinctive sheet-like nanostructures and the capacity for photothermal conversion have rendered graphene-based nanocomposites highly favorable for optical therapeutic applications, including photothermal treatment (PTT), photodynamic therapy (PDT), and theranostics. This review highlights the current state and benefits of using graphene-based nanocomposites in cancer diagnosis and therapy and discusses the obstacles and prospects of their future development. Then we focus on graphene-based nanocomposites applications in cancer treatment, including smart drug delivery systems, PTT, and PDT. Lastly, the biocompatibility of graphene-based nanocomposites is also discussed to provide a unique overview of the topic.

RESUMEN

PURPOSE: Healthy cancer survivorship involves patients' active engagement with preventative health behaviors and follow-up care. While clinicians and patients have typically held dual responsibility for activating these behaviors, transitioning some clinician effort to technology and health coaches may enhance guideline implementation. This paper reports on the acceptability of the Shared Healthcare Actions & Reflections Electronic systems in survivorship (SHARE-S) program, an entirely virtual multicomponent intervention incorporating e-referrals, remotely-delivered health coaching, and automated text messages to enhance patient self-management and promote healthy survivorship. METHODS: SHARE-S was evaluated in single group hybrid implementation-effectiveness pilot study. Patients were e-referred from the clinical team to health coaches for three health self-management coaching calls and received text messages to enhance coaching. Semi-structured qualitative interviews were conducted with 21 patient participants, 2 referring clinicians, and 2 health coaches to determine intervention acceptability (attitudes, appropriateness, suitability, convenience, and perceived effectiveness) and to identify important elements of the program and potential mechanisms of action to guide future implementation. RESULTS: SHARE-S was described as impactful and convenient. The nondirective, patient-centered health coaching and mindfulness exercises were deemed most acceptable; text messages were less acceptable. Stakeholders suggested increased flexibility in format, frequency, timing, and length of participation, and additional tailored educational materials. Patients reported tangible health behavior changes, improved mood, and increased accountability and self-efficacy. CONCLUSIONS: SHARE-S is overall an acceptable and potentially effective intervention that may enhance survivors' self-management and well-being. Alterations to tailored content, timing, and dose should be tested to determine impact on acceptability and outcomes.

RESUMEN

Sudan has been under an armed conflict between the Sudanese Armed Forces and the Rapid Support Forces (RSF) militia since April 15, 2023. The conflict has turned the country into the largest internal displacement humanitarian crisis with 9.05 million internally displaced persons including 2.2 million children younger than 5 years and caused 1.47 million Sudanese to flee the country as refugees. The conflict has had a major destructive impact on the health system, which has incurred targeting with air raids, ground invasion, vandalization, looting of assets and supplies, and killing of doctors, nurses, and other health personnel. Khartoum Oncology Hospital, Sudan's main cancer hub for treatment, diagnostics, and research has become nonfunctional as a result of the conflict. The National Cancer Institute in Wad Medani, the second largest hub, faced a similar fate as the conflict spread to Al-Gezira State. Patients with cancer have been displaced multiple times in Sudan with grave consequences on the continuity of care, worsening of their disease outcomes and palpable negative impacts on children. The oncology workforce in Sudan have themselves been displaced yet are working hard to provide services and care for patients under impossible circumstances. Sudan's doctors in diaspora have rallied to provide support but they face multiple obstacles. As the conflict continues to spread, we call upon the WHO, the United Nations Children's Fund, St Jude Hospital, and all relevant partners to implement an immediate evacuation operation with urgent air lifts of the affected children to continue their cancer care in neighboring countries as was done in Ukraine and Gaza.

RESUMEN

The global incidence of cancer continues to rise, posing a significant public health concern. Although numerous cancer therapies exist, each has limitations and complications. The present study explores alternative cancer treatment approaches, combining hyperthermia and photodynamic therapy (PDT). Magnetic nanoparticles (MNPs) and amine-functionalized carbon quantum dots (A-CQDs) were synthesized separately and then covalently conjugated to form a single nanosystem for combinational therapy (M-CQDs). The successful conjugation was confirmed using zeta potential, Fourier transform infrared spectroscopy (FT-IR), and UV-visible spectroscopy. Morphological examination in transmission electron microscopy (TEM) further verified the conjugation of CQDs with MNPs. Energy dispersive X-ray spectroscopy (EDX) revealed that M-CQDs contain approximately 12 weight percentages of carbon. Hyperthermia studies showed that both MNP and M-CQDs maintain a constant therapeutic temperature at lower frequencies (260.84 kHz) with high specific absorption rates (SAR) of 118.11 and 95.04 W/g, respectively. In vitro studies demonstrated that MNPs, A-CQDs, and M-CQDs are non-toxic, and combinational therapy (PDT + hyperthermia) resulted in significantly lower cell viability (~4%) compared to individual therapies. Similar results were obtained with Hoechst and propidium iodide (PI) staining assays. Hence, the combination therapy of PDT and hyperthermia shows promise as a potential alternative to conventional therapies, and it could be further explored in combination with existing conventional treatments.

RESUMEN

A cutting-edge non-invasive cancer treatment method called boron neutron capture therapy (BNCT) allows for the removal of cancerous tumor cells with the least possible damage to healthy tissue. It involves the exposure of cancer cells with low-energy thermal neutrons, boron-10 (10B) cellular uptake causes cancer cell death by producing alpha particles and recoiling lithium-7 (7 Li) nuclei. Despite positive outcomes from clinical trials conducted all around the world, these substances have relatively limited tumor selectivity or low boron content per molecule. The development of new boron delivery agents with more selectivity and enhanced boron loading would advance this technique and promote its use in clinics as a primary cancer treatment. As peptide-binding cell surface receptors are typically overexpressed on cancer cells, they can be seen as interesting targets for targeted tumor therapy. The attachment of meta-carboranes to peptide conjugates that target tumor cells specifically by their overexpressed receptors may be a method to get around these problems. A state-of-the-art overview of current developments in the application of BNCT for cancer targeted therapy via peptide conjugation is the goal of this review.
